Abstract

Greenhouse adalah bangunan yang secara khusus dirancang untuk melindungi tanaman dari kondisi lingkungan eksternal yang tidak menguntungkan, serta mengatur lingkungan internal guna menciptakan kondisi ideal yang mendukung pertumbuhan tanaman secara optimal. Namun, sistem monitoring konvensional di Greenhouse mengalami masalah tingginya penggunaan kuota internet dan packet loss akibat ketergantungan pada WiFi access point (AP). Dalam penelitian ini, dikembangkan sebuah sistem monitoring tanaman di Greenhouse menggunakan arsitektur master-slave menggunakan protokol ESP-NOW untuk mengatasi masalah packet loss. Selain itu, algoritma change detection diterapkan pada node master guna mengurangi pengiriman data yang redundan serta memperkecil ukuran paket data yang dikirimkan. Hasil pengujian menunjukkan bahwa tingkat packet loss mencapai 1,43% dari total 222.793 pengiriman data selama tiga hari, yang termasuk dalam kategori "sangat bagus" menurut standar TIPHON. Algoritma change detection juga berhasil mengurangi estimasi penggunaan kuota internet bulanan hingga 82,4 MB. Sistem yang dikembangkan ini terbukti efektif dan efisien dalam memantau kondisi lingkungan tanaman dengan tingkat keandalan yang tinggi, sekaligus mampu menghemat penggunaan kuota internet.

Abstract

The monitoring system for water level in peatland is crucial for detecting the potential for fires, especially during the dry season. This study develops a water level monitoring system using a water float level sensor capable of detecting changes in water level in real-time. Data from the sensor is transmitted via the LoRa SX1278 Ra-02 module, enabling long-range data transmission. The system was tested under two conditions: Line of Sight (LoS) and Non-Line of Sight (NLoS), to measure the signal strength indicated by the Received Signal Strength Indicator (RSSI). In the LoS condition, the best RSSI value was recorded at -63 dBm at a distance of 15.5 meters, while in the NLoS condition, the lowest RSSI value reached -110 dBm at a distance of 148 meters. The results show that this system is effective in monitoring water levels in peatland with reliable data transmission, even in remote areas. The integration of the water float level sensor and LoRa technology in this system has the potential to be a valuable tool for preventing peatland fires through real-time monitoring of water conditions.
